A jury's been told that a man accused of murdering a Northampton family is unlikely to have been "severely depressed".
Psychiatrist Dr Phillip Joseph, for the prosecution, said Anxiang Du had not "given up the fight", and had been able to work and visit casinos in the months before the killings.
The defence argue Du would never have killed if he'd not been depressed.
The 54-year-old from Coventry denies murder, but admits killing the Ding family in April 2011.
A Judge has described how Anxiang Du was a "man on a mission" on the day he killed a Northamptonshire family.
Today the man who repeatedly stabbed a family of four was found guilty of murder in what was described in court as a cold-blooded massacre.
A killer who massacred a family of four was able to flee the country after police mishandled a 999 call from one of the victims.
